IMPROVEMENT IN STOVE-GRATES.

Specification forming part of Letters Patent No. 146,456, dated J anuaryl, 1874 application filed July 3, 1873.

To all whom it may concern:

Be it known that I, JOHN B. HUNT, of Milford, Hunterdon county, New Jersey, have invented a new and useful Improvement in Stove Gratos; and I do hereby declare the following to be a clear and exact description y of the nature thereof, sufficient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings, making part of this specication, in which- Figure l is an inside view of the device e111- bodying my invention. Fig. 2 is a front view thereof. Fig. 3 1s a transverse vertical section in line w or, Fig. 2. Fig. 4 is a bottom view. Fig. 5 is an end view of a partition-plate. Fig. 6 1s` a side view thereof, and Fig. 7 is a top View thereof.

Similar letters of reference indicate corresponding parts in the several gures.

This invention relates to the construction of a stove-grate, wherein a portion thereof may be in service and the other portion may-begrate B, `consisting ofthe vertical portion ay and the horizontal portion b. The base or horizontal portion b of the grate is formed with circular openings C, in which are fitted rotaryT grates D, which rest on the edges of the portion b, surrounding the openings G. E represents notches or ways, which are formed in `the portion b at points surrounding the openings C, and communicate with the latter, and said notches or ways extend in opposite directions in lsuch manner that they are at the sides of a line drawn centrally' and transversely through the grate, as indicated at y y, Fig. 4.

The under side of the revolving grate D is formed withl an eye, F, which extends from one portion thereof, and aprojection, G, which ex- .tends from a portion opposite to that of the eye F, so that, when the revolving grat-e is in proper position, the eye-F and projection G come beneath the horizontal portion b of the grate B, and thus prevent rising of the grate D. H represents an implement, 011e end of which is formed with a head to enter and engage with the eye F of the grate D, and the other end is forked or clawed, for purposes to be stated. When this implement H is applied to the eye F, the grate may be readily shaken, and the notches are so disposed that, with ordin ary shakin g, the projection G does not reach a notch, E, whereby the grate D will not be raised from the portion b; but, when it is desired to raise and remove the same, then a full turn is imparted to said grate, in order to have the projection G coincide with one of the notches E, and the grate is free to be lifted n from its place of rest.

The mode of applying'the grate D is by introducin g the eye Funder the portion b, opposite to one of the notches E, and bringing the projection G and said notch in line with each other.' The grate D then iits in the opening C, and, by a turn of the former, the projection again engages with the under side of the portions b of the grate B.

J represents a plate, which is adapted to bc fitted vertically, centrally, and transversely in the grate B, and thus divide the grate into two fire-chambers, for purposes ofhavingafire only in one side or chamber of the grate, or a good ire in one chamber and a low iire in the other chamber. This partition-plate has a foot K, which enters the central grate-opening c in the base b of the grate B, and a lockingfoot,` L, which catches under the portion b at the rear thereof, as shown at f, Figs. 1, 3, and 4. Lugs M are formed with or secured to thehinner face of the portion a of the grate B, to einbrace the forward portion of the partition-plate J, and thus, by means of said lugs, the feetK L, and the top plate N of the stove, the plate J is lirmly held in place and prevented from rising or shifting laterally. On the upper edge of the plate J there may be formed notches P, Y

which leave a neck, R, for engagement of the forked or clawed end of the implement H,

whereby, by applying the latter, the plate may belifted from the grate or applied thereto with# out the fi n gers or hand touching said plate 5` but the notches P and implement H are not essential parts of the invention, and no claim is laid thereto.

When fire is required or desired in the entire grate, the partition J is removed and the grate B will then be found to act in a manner similar to ordinary grates, the central grate opening d serving as a central draft and raking opening, and the various parts presenting no obstacle to the free operation of the grate.

When the partition is applied and one ofthe chambers is not required for use, such chamber may be cleansed by operating the grate D, and Without disturbing the other chamber.

Having thus described my invention,wl1at I claim as new, and desire to secure by Letl. The projection F and eye Gn on the under side of the revolving grate D, in combination with the notches 0r Ways E of the openings C in the portion b of the grate B, arranged and operating as stated.

2. The grate consisting of the portion b, formed With openings C C and Ways E, and

the portion a, With lugs M, in combination with JOHN B. HUNT.
